Hello all, I recently purchased a 1990 F-250 with the 7.3 IDI International and was wondering what i can do to increase performance. Its a 4x4 with automatic. Its gonna be a daily driver/weekend off road rig. All help would be much appreciated as I know almost nothing about these engines.

 

Tweak the injection pump a little bit and put a turbo on it.

 

Congrats on the new truck!
